I really like this custom. The good thing for a project like this is that it gives you a good reference point. If you really feel you'd want to reattempt this piece again, you've already tackled it once. Now you have a road map. Hone in on what works, and examine what you feel didn't work for you. Make some notes to your self and keep moving on

You may find yourself moving on to many other projects and returning to this one, or you may find yourself really thinking about reconsidering tackling this piece until you're totally satisfied. It can be hard determining which to do, but I've found both to be effective on a case-by-case basis.
